IMPROVEMEN'I' IN SAFETY-HOOKS.

Specification forming part of Letters Patent No. 2 [9.677, dated September 16, 1879; application filed.

May 22, 1879.

To all whom it may concern.'

Be it known that I, HENRY BLAKEMAN, of Jefferson City, in the county of Jefferson andY Territory of Montana, have invented a new and Improved Safety-Hook, of which the following is a speciiication.

The object of this invention is to prevent the bucket or other object suspended from the hook from slipping therefrom. It consists in providing the hook with a keeper sliding on the shank to and from the point thereof, and a spring for locking it in place against the end of the hook.

In the accompanying drawings, Figure 1 is a sideview of the hook,partly in section,show ing the position of the keeper when closed against the end of the hook. Fig. 2 is an edge p view of the hook and keeper from the front,

and Fig. 3 is a cross-section of Fig. 1 on line m m.

Similar letters of reference indicate corre'- sponding parts.

Referring to the drawings, A is the hook, B is the shank thereof, and C is the eye by which it is suspended from the rope or chain.

In the front edge ofthe shank is aslot, a, in which is set a spring, b, with its end next to the eye secured by'a pivot, c, passed through the shank. D is the keeper, with two rightangular arms, d d', the latter extending backward against the front edge ofthe shank, and having a rectangular socket, e, through which the shank is passed, while the former extends in the opposite direction in line with the end f of the hook. The end of arm d has a socket, g, which receives the pointed end of the hook, as clearlyr shown in Fig. 1.

The keeper slips freely back and forth on over the hook the keeper is then pushed down until its socketed en d bears against the pointed end of the hook, in which position it is retained by the spring b. When thus arranged. it will be impossible for the bucket to slip from the hook. I

Iam aware that it is not new to use a sliding spring-tongue having its end notched to engage acorresponding notch in the hook; but

A safety-hook composed of the hook A, with shank B, the eye C, and the sliding keeper D, and having the spring b fastened at-one end to the upper side of its shank extended in groove a and adapted to rise behind the slide and lock it, as described. l
